APPARATUS FOR SHAPING MOLDS.

SPECIFICATION forming part of Letters Patent No. 363,620, dated May 24, 1887.

.To all whom it may concern.-

Be it known that 1, JAMES FLEMING, of 72 Federal street, in the city of Troy, county of Rensselaer, state of New York, have invented a new and useful Apparatus for Brushing and Shaping Molding-Forms, of which the following is a specification.

My invention relates to improvements in apparatus for brushing and shaping the interior of molding-forms. such as are used for casting cylindrical forms of metal; and it consists in providing the mold with sectional gage-plates of semicircular form, each half or section of which is adapted to remain with its section of the mold when the latter is removed, or when the two halves of the mold are connected, all as will be hereinafter described, and pointed out in the appended claim.

Accompanying this specification to form a part of it there is a plate of drawings containing four figures, illustrating :my invention, with the same designation of parts by letterreference used in all of them. Of these illustrations, Figure 1 is a side elevation of a molding jacket or flask, used to produce one-half of a cylindrical form, said jacket being shown as adapted to have at each end a gageplate attached thereto by means of dowels. Fig. 2 shows one of said gage-plates as detached from the flask or jacket. Fig. 3 shows the jacket or flask illustrated at Fig. l united with another jacket having the same half-cylindrical form to produce a casting having a cylindrical exterior form. Fig. 4shows the templet or shaping-tool used in connection with the interior of the jackets and the end gage-plates to give a well-defined and true finish to the interior of the mold made in the flasks or jackets.

The several parts of the apparatus thus illustrated are designated by letter-reference, and the function of the parts is described as follows:

Theletter J designates one of the jackets, of which there are two interiorly and exteriorly alike, each representing one-half of a cylinder, and these jackets are adapted to connect by means of side flanges and dowels made in the usual way. The letter J designates the other jacket. The interior rounded out surfaces of these jackets are provided with the usual sandclinching projections, indicated by the dotted line on".

The letter G designates a gage-plate composed of two sections or halves, which is designed to overlap the opening in themold and lie flush with the lining of sand, and is adapted by means of dowels (Z to attach to the top of each of the jackets, and G" gage-plates adapted to attach to the bottom of each of the said jackets, and designed to overlap the end of the opening in the mold, and the letter B designates a blade or templet used for finishing up and trimming the said lining of thej ackets.

The letters Z designate a lining of cohesive molding-sand that has been pressed into the clinching projections upon the interior cylindrical face of the jackets. When this lining is applied, it is made to project in thickness inwardly beyond the gageplates G and G. This lining of sand is turned down and scraped off by the templet or blade 13 until it is in line with the gage-plates, as shown at Fig. 1.

The templet-blade B is made with straight side edges like astrickle; but it is also provided with a groove through'its longitudinal center and with end handles for operating it. The function of the groove is to gather up the sand scraped from off the interior of the form while being finished. The gage-plates G' and G are held in position by dowels, which are passed through the perforations in the semicircular plates and the perforations on the flanges on the mold, and the two halves of said mold are connected by the dowels passing through the perforations in the flanges thereof while the rounded interior of the mold. is being finished up by the templet-blade, the said gage-plates forming no part of the cap or baseplatc, as in older devices.

With an apparatus thus arranged and operated the jacket linings are finished up so as to have true surfaces, and the work is done rapidly and at much less cost than when done in the usual manner, and the end pieces beingin halves of semicircular form allows each half of the mold to retain its half of the plate. I am aware that prior to my invention asimilar patent was granted in England in 1870, and numbered 2,819, and I do not claim such construction as therein shown; but,

I IO

Having thus described my invention, what I Signed at Troy, New York, this 24th day of claim, and desire to secure by LettersPatent, October, 1885, and in the presence of the two 10 iswitnesses whose names are hereto written.

Combined with the mold constructed as de- T i 5 scribed, the gage-plates G G, composed of 4 JAMES FLEMILG' two halves of semicircular form, having the \Vitnesses: perforations to receive the pins (7, as shown, N. E. HAGAN,

and for the purpose set forth. CHARLES S. BRINTNALL.
